Background
The wetland not only provides various resources for the production and the life of human beings, but also has huge environmental functions and benefits, and has irreplaceable functions of other systems in the aspects of resisting flood, regulating runoff, storing flood, preventing drought, controlling pollution, regulating climate, controlling soil erosion, promoting silt, making land, beautifying environment and the like, so the wetland is known as 'the kidney of the earth'. In the world natural protection outline, the wetland, the forest and the ocean are called as three global ecosystems, the function and the benefit of the wetland are ignored while the urban efficiency is pursued on one side, the urban wetland has the defects of reduced area, degraded function and serious pollution, particularly the eutrophication phenomenon is prominent, a large amount of wetland is eaten by the urbanization process, and the water quality of the urban wetland is continuously reduced due to industrial and domestic sewage.
People can produce a large amount of sewage and wastewater every day in life, the sewage is generally produced by flushing a toilet, the wastewater is used for washing vegetables, clothes, rice and the like, the raw and small sewage and wastewater in cities are discharged to a sewage treatment center through a pipe network for centralized treatment and then discharged to rivers, generally, 5 ten thousand people need to build a sewage treatment plant, the sewage treatment occupies a large amount of land, and the purification cost of decontamination water is high.
At present, many communities are built with hydrophilic landscape areas to create hydrophilic atmosphere, but as the communities are put into use, the water landscape becomes a 'stain' affecting the living quality due to the deterioration of water quality or the dry water source. Some property businesses of some districts bury some water pools by soil, the water landscape becomes a genuine 'waterless landscape', the water landscape of the districts becomes a decoration, and the important reason is that the later-period operation and maintenance cost is high. At present, tap water or natural rainwater is mostly used for building water landscape on a building, and daily operation and maintenance cost very much water and electricity. In view of the existing payment capacity of the property fees of the residential areas, the property management company has no capacity or power to manage the water landscape under the condition that 'special expenses' are not collected. The water landscape built by the pure silver is idle or even abandoned, which not only influences the community environment, but also causes unnecessary waste. Although, departments such as planning, residential building and the like should make some targeted guidance and specifications for water landscape design, construction and operation management of urban residential districts. Meanwhile, it is recommended to establish a rainwater recovery system to reduce its daily maintenance cost, but in a dry area with little rain, the effectiveness of the rainwater recovery system may be very low.
How to utilize a large amount of waste water produced in a community every day into a hydrophilic landscape, so that the water resource is fully utilized, the waste water treatment cost can be saved, the construction cost of a waste water treatment plant can be saved, the social cost is saved, and the waste water can be directly discharged into rivers and can also permeate into the underground to supplement underground water after being purified through self-circulation.
